Preset Button
Operation
The Preset button on the front panel of the E5810 is used to reset the E5810
to its default configuration values (preset at the factory). As shown in the
figure on the next page, the Preset button has two modes of operation:
If you depress the Preset button and release it in <10 seconds, only
the E5810 password is temporarily changed and is reset to its
default value (E5810). If you cycle power or reboot the E5810, the
E5810 will return to the actual password that was previously set. All
existing configuration values remain unchanged.
If you depress and hold the Preset button for 10 seconds or more, all
configuration values are reset to their factory default values and the
E5810 is rebooted. All network connections to the E5810, if any, are
also terminated without any cleanups.

Feature
Description
Remote access to
instruments via LAN
Access and control up to 14 GPIB and/or one RS-232 instrument via a
10BASE-T/100BASE-TX Ethernet. The E5810 detects the network
and configures itself to the appropriate speed. The E5810 has a
standard RJ-45 LAN connector. You can use adapters to connect other
interface types, such as optical or wireless LAN.
I/O Software Included
The E5810 includes the Agilent IO Libraries Suite, which includes
Agilent Virtual Instrument Software Architecture (VISA), VISA COM,
Standard Instrument Control Library (SICL), and several I/O utilities.
This standard software provides compatibility with different hardware
and software vendors. It provides the I/O software layer used when
accessing the E5810. You can use a standard programming language,
such as Visual Basic, Visual C++, Agilent VEE, etc.
The E5810 supports all I/O application operations provided by VISA,
VISA COM, SICL, and Agilent VEE. The E5810 is supported on
Microsoft Windows XP/Vista/7/8/Server 2008 R2.
You can also use the Agilent IntuiLink software (included with some
Agilent products) to download data and send waveforms to the source,
with no programming.
Supports DHCP
Protocol
The E5810 supports Dynamic Host Configuration Protocol (DHCP) to
get its IP address. Although the E5810 defaults to using DHCP, you
can turn DHCP OFF and statically assign the E5810 IP address.
Ease of Use
Built-in Web access and front panel display allow you to easily set up,
configure, and use the E5810. You can connect multiple E5810s in a
test system. Each E5810 creates a separate GPIB bus.

E5810A Description
E5810A Software/Firmware
Typical Network Operation
The E5810 provides a network gateway between network-equipped
computer systems and GPIB and/or RS-232 based instruments. The
gateway enables users to obtain measurement data either locally or
remotely from GPIB and/or RS-232 instruments. See “Typical Network
Connections” in this chapter for typical connections to Enterprise or Local
Networks or to a PC.
The E5810 connects a local area network (LAN) from the computer system
to the GPIB and/or RS-232 buses. Network-equipped computer systems
that are supported for use with the E5810 include PCs with Windows XP/
Vista/7/8/Server 2008 R2. Using the client/server model of computing, the
computer system is the client, and the E5810 is the server.

Thus, applications running on the computer system can transparently
interface to GPIB and RS-232 based instruments over the LAN. Since
several computer systems can access the E5810, groups of users can share
access to the same GPIB and/or RS-232 instruments via the E5810. In
addition, existing I/O applications that are supported with the E5810 and are
designed for GPIB or RS-232 can use the E5810 without modification other
than an address change.
The E5810 and its attached instruments can be placed anywhere on the
network (rather than with a particular controller or server computer system).
This includes networks which span different geographic locations, such as
when networked computer systems are located at several different sites.
Thus, GPIB and RS-232 instruments can be located where they are most
convenient. In addition, you can have more than one E5810 on a network,
providing “clusters” of GPIB and/or RS-232 instrumentation at different
locations.

E5810A Software/Firmware
Software/Firmware Architecture
To program instruments from your PC via the E5810 using a programming
language such as C or Visual Basic, you must install and configure the
Agilent IO Libraries Suite on the client PC.
Client System
Architecture
As shown in the following figure, the client (PC) system contains the VISA
LAN client software as well as the TCP/IP LAN software needed to access
the E5810. The E5810 contains LAN server and TCP/IP LAN firmware so it
acts as the LAN server.
The VISA LAN client software is also known as the Remote IO Client
software. It is part of the Agilent IO Libraries Suite. The LAN server software
is also called the Remote IO Server software.
The VISA LAN client software uses the TCP/IP LAN protocol suite to pass
messages between the client system and the server (the E5810). Therefore,
the client sends I/O requests over the network to the server. The server then
executes those I/O requests on the appropriate GPIB and/or RS-232 based
instrument(s) connected to the server.

E5810A Software/Firmware
How IO Application
Software Works
With the E5810
Before trying to perform an I/O application operation on the E5810 GPIB
interface and the GPIB bus, the Remote IO Client software in the client
computer system establishes a network connection to the remote I/O server
(the E5810). Once the client establishes a connection, the client can begin to
send I/O requests to the E5810.
The E5810 (remote I/O server) can have multiple clients connected and
being serviced at any given time. The maximum number of concurrent client
connections depends on memory usage in the E5810, including the number
of clients and the number of current sessions running on those clients.
However, up to 16 client connections can be running concurrently. Thus, if
the maximum number of client connections to the E5810 has not been
exceeded, the connection is allowed to occur.
Although several instruments can be connected to the E5810 GPIB bus,
only one I/O application operation can occur on the GPIB bus at any given
time. Therefore, once a client’s request begins to execute on the GPIB, all
other client requests for operations on the GPIB must wait until the current
client request completes. Client requests are serviced in a first come, first
served manner, unless they are prohibited by interface or device locks.
If a client has a sequence of I/O application operations to perform that
should not be preempted, the client should obtain a lock on the E5810 GPIB
interface or device. Once the client’s sequence has completed, it should
release its lock, allowing access for other clients.
When a client closes a connection, the E5810 frees up the resources
allocated to that client, including any locks, pending I/O requests, memory
usage, etc.

Typical Network IP Addressing
This section describes typical Enterprise network IP addresses and subnet
addresses on the network. This figure shows a typical Enterprise network,
consisting of a Router (Gateway), a corporate Dynamic Host Configuration
Protocol (DHCP) Server, and a subnet consisting of six hosts (two E5810s
and four host PCs.) The Router sends packets of information to each host,
based on the IP address of the host. The subnet is defined by the Subnet
Mask for the IP addresses on the subnet.

E5810A Description
E5810A Software/Firmware
Subnet Addressing
A Subnet Mask is used to determine to which subnet an IP address belongs.
An IP address has two components: the network address and the host
address. For example, assuming IP address 156.215.117.109 is part of a
Class B network, the first two numbers (156.215) represent the Class B
network address and the second two numbers (117.109) identify a specific
host on this network. See the Glossary for a description of a Class B
network.
For the subnet in the figure, an example IP address for E5810 #1 is
156.140.104.72, where 156.140 represents the network address and 104.72
represents the E5810 #1 host address. An example IP address for E5810 #2
is 156.140.104.75, where 156.140 represents the network address and
104.75 represents the E5810 #2 host address.
E5810 IP Address
Assignment
For the E5810 to operate on an Enterprise network, three addresses must
be identified: E5810 IP Address, Subnet Mask, and Default Gateway
Address.
If the Enterprise network supports Dynamic Host Configuration Protocol
(DHCP), the E5810 will automatically receive an IP address, Subnet Mask,
and Default Gateway from the DHCP Server. If the network does not support
DHCP, the E5810 IP address must be configured manually.
In addition, if the network supports Domain Name Service (DNS), an E5810
Hostname can be configured. This can be done in one of two ways:
The DNS Server IP Address is provided by the DHCP Server (this is
transparent to the user).
A DNS Server IP address is supplied by the System Administrator
and entered on the Configuring your E5810 LAN/GPIB Gateway page.

What is a Local Network?
A local (peer-to-peer) network is a network consisting of a computer with an
Ethernet port and an E5810 or a set of networking devices that are
networked together but are not connected to an Enterprise network. The
figure on the next page shows example configurations for Local networks
with hub/switch or crossover cable connections.
Local Network
(Hub/Switch)
Connections
In a typical Local network (isolated LAN), a hub or switch may or may not act
as a Dynamic Host Configuration Protocol (DHCP) Server. For Local
Network connections, the E5810 is not visible on the Enterprise network. For
this configuration, multiple PCs can communicate with the E5810 via the hub
or switch.
Direct PC
(Crossover Cable)
Connections
For direct PC connection to the E5810, a crossover cable is connected from
the E5810 LAN port to a LAN card on the PC. There are no connections to
an Enterprise network. This setup is typically used for local configuration.
For this configuration, only a single PC can communicate with the E5810 via
the crossover cable.

After connecting the E5810 to a Local network, plug the E5810 AC power
cord into an AC outlet and observe the power-on sequence. When the
power-on sequence is complete, the default IP address of the E5810 is
displayed on the second line of the front panel display. A typical display
follows. See Chapter 1, “E5810A Description” for power-on sequences.
NOTE
Local networks may not have a DHCP Server. Since, by default, the
E5810 tries to find a DHCP server until a timeout value is reached, it may
require up to 75 seconds for the E5810 to display its default static IP
address (169.254.58.10).
NOTE
The E5810 detects duplicate IP addresses and will not start operation if
its IP address is already in use. If you try to simultaneously attach multiple
E5810s without changing each unit’s default static IP address, some
E5810s may not start operation.
To prevent this from happening, add a single E5810 at a time to the
network and configure each E5810 to a unique IP address before adding
additional E5810s.

This section gives guidelines to configure the E5810 on a Local network.
This section applies if you plan to configure the E5810 for eventual
installation on a non-DHCP Enterprise network or plan to configure the
E5810 for eventual use on the Local network.
NOTE
When configuring the E5810, we recommend you change the default IP
address to a unique IP address for each E5810 being added to the
system. Otherwise, since the E5810 detects duplicate IP addresses,
some E5810s added to the system may not operate. See Chapter 3,
“Using E5810A Web Access” for details on setting E5810 parameters.
Establishing
Communication
With Your PC
Whether your Local network includes a hub/switch or a crossover cable, the
first step in configuring the E5810 is to establish communication between
your PC and the E5810. To do this, the PC and the E5810 must be on the
same subnet.
One way to put the PC and the E5810 on the same subnet is to use
route add <E5810 IP Address> <PC IP Address> from the
MS-DOS prompt. For example, if IP address of your PC is 155.139.103.152
and the E5810 IP address is 169.254.58.10 (the default), use one of the
following:
! route is lost when the PC is rebooted
route add 169.254.58.10 155.139.103.152
or
! route persists when the PC is rebooted
route -p add 169.254.58.10 155.139.103.152
After communication has been established, you can set any required
configuration parameters for the E5810 by using the E5810 Web access.

including:
Using Interactive IO for Communication
Using Supported Programming Languages
NOTE
You can also communicate with (but not program) installed GPIB and/or
RS-232 instruments using the E5810 Web access, whether or not you
have installed and configured the Agilent IO Libraries Suite. See Chapter
3, “Using E5810A Web Access” for details.
Using Interactive IO After the E5810 has been configured and you have connected your GPIB
for Communication and/or RS-232 instruments to the E5810, you can verify communication
between your PC and the instruments by using the Interactive IO utility or by
using VISA or SICL commands with supported programming languages.
This section shows one way to use Interactive IO to verify instrument
communication.
NOTE
Once your remote interface(s) and instrument(s) have been configured in
Connection Expert, if you can see them in the Connection Expert explorer
and see their IDN string information in the detail pane then
communication has been verified. Interactive IO allows you to manually
verify communication and send specific commands to your instrument.

User’s Guide. Also see the Agilent Connectivity Guide and Agilent
IO Libraries Suite Online Help for further information and guidelines on
programming with the Agilent IO Libraries.
Addressing
Instruments using
VISA and Remote
IO Client
Once you have created a remote GPIB or remote serial interface in
Connection Expert, you can use ordinary GPIB or serial addressing in your
VISA or VISA COM programs to address instruments on these interfaces.
The Remote IO Client software maps TCPIP address requests into
appropriate interface type (GPIB or ASRL) addresses; thus the IP address
and hostname of the E5810 do not appear in the instrument address. This
makes it possible to use existing programs written for GPIB or ASRL without
having to modify code.
See “Configuring a Remote Serial Interface” on page 65 to configure a
remote GPIB or remote serial interface. VISA programs can then use
addresses such as GPIB0::22::INSTR (for GPIB) or ASRL1::INSTR (for
RS-232). Use these addresses in your viOpen() call as follows:
viOpen (...”GPIB0::22::INSTR”...)
viOpen (...”ASRL1::INSTR”...)
Addressing
Instruments using
VISA and TCPIP
Interface
Although remote GPIB and remote serial interfaces are the most convenient
way to configure and program instruments on your E5810, you may choose
not to use them. For example, if you are using another vendor’s I/O software
rather than the Agilent IO Libraries Suite, your I/O software probably does
not support remote interface addressing. (At the time of this writing, only
Agilent software supports remote interface types.)
If you are not using remote interfaces, you will address your instruments as
TCPIP resources in VISA. These addresses include the IP address or
hostname of the E5810 as well as the SICL address of the device on the
E5810.
Use these addresses in your viOpen() call as follows. These examples
assume that the VISA interface ID of your TCPIP interface is “TCPIP0”. (You
can specify this interface ID with the Connection Expert utility; “TCPIP0” is
the default VISA ID for the default TCPIP interface.)
viOpen (...”TCPIP0::my_IP_address::gpib0,22::INSTR”...)
viOpen (...”TCPIP0::my_IP_address::COM1,488::INSTR”...)
70
Chapter 2
Installing the E5810A
Installing and Configuring Agilent IO Libraries Suite
Addressing
Instruments with
SICL
SICL addresses include the IP address or hostname of your E5810 as well
as the SICL address of the device on the E5810, and optionally the protocol
to be used. Some example addresses for SICL programs follow. These
examples assume that the SICL interface ID of your TCPIP interface is “lan”.
(You can specify this interface ID with the Connection Expert utility; “lan” is
the default SICL ID for the default TCPIP0 interface.)
lan[my_IP_Address]:gpib0,22
lan;vxi-11[my_IP_Address]:gpib0,22
lan[my_IP_Address]:COM1,488
lan;sicl-lan[my_IP_Address]:gpib0,11
NOTE
At the time of this writing, National Instruments I/O software does not
support the SICL-LAN protocol, but only the VXI-11 protocol. Because
RS-232 instruments are only supported by SICL-LAN and not VXI-11, you
cannot use National Instruments I/O software to program an RS-232
instrument on your E5810.

E5810 Configuration An alphabetical listing of E5810 configuration parameter descriptions and
Parameter
applicable default (factory-set) values follows. The E5810 uses the default
Descriptions
configuration values until you change any value and save/reboot. The
E5810 also uses the default values when you press and hold down the
Preset button for >10 seconds.
Parameter
[Default]
Description
Default Gateway
[0.0.0.0]
This value is the IP address of the default subnet gateway that allows the
E5810 to communicate with systems that are not on the local subnet.
This is the default subnet gateway where packets are sent which are
destined for a device not on the local subnet, as determined by the
subnet mask setting. Only one default subnet gateway can be configured.
A value of 0.0.0.0 indicates that no subnetting is to be done.
Description
[Factory-Set]
The default description consists of “E5810 LAN/GPIB Gateway” followed
by the Ethernet (MAC) address. The Ethernet address is printed on a
label on the underside of the E5810.
A typical description is: Agilent E5810 00-30-D3-05-00-23, where
00-30-D3-05-00-23 is the Ethernet address. The description is the “UPnP
Friendly Name” of the E5810 that will automatically be displayed on
UPnP (Universal Plug and Play) enabled LAN hosts.
When the E5810 is connected to the LAN, it broadcasts its presence to
the network if UPnP is enabled. UPnP clients will then see this E5810 in
My Network Places, listed by this Description. A Friendly Name can be up
to 39 characters, including spaces.
Domain Name
Server (DNS)
[0.0.0.0]
A DNS Server is an Internet service that translates domain names into IP
addresses and vice-versa. Every time you use a domain name, a DNS
Server must translate the name into the corresponding IP address.
For example, the domain name www.example.com might translate to
198.105.232.4. The DNS system has its own network. If one DNS Server
does not know how to translate a particular domain name, it asks another
DNS Server, etc. until the correct IP address is returned, if available.

Domain Name
Server (DNS)
(cont)
[0.0.0.0]
Description
A DNS Server is an Internet service that translates domain names into IP
addresses. Every time you use a domain name, a DNS server must
translate the name into the corresponding IP address. For example, the
domain name www.example.com might translate to 198.105.232.4.
The DNS system is distributed. If one DNS server does not know how to
translate a particular domain name, it asks another DNS server, etc. until
the correct IP address is returned. If DHCP is used, a DHCP Server may
provide a DNS Server IP address to the E5810 (this is transparent to the
user). If the user configures a DNS Server, the E5810 will try to use that
Server first.
This parameter shows the IP address of the domain name Server. More
than one address may be listed on the Current Configuration of the E5810
LAN/GPIB Gateway page. Up to two of these values may have been
returned by the DHCP Server during startup. Only one static value can be
input on the Configuring your E5810 LAN/GPIB Gateway page.
The DNS Server provides a Hostname, given an IP Address, for a LAN
device based on entries in its DNS lookup table. If DHCP is OFF and you
do not specify a DNS Server or if Dynamic DNS is not available on your
enterprise LAN and your IP Address is not in the DNS lookup table on the
DNS Server, your Hostname will be unknown and you must address the
E5810 only by its IP Address. The Hostname is not a required entry.
Dynamic Host
Configuration
Protocol (DHCP)
[ON]
DHCP is a protocol for assigning dynamic IP addresses to devices on a
network. DHCP supports a mix of static and dynamic IP addresses. The
two options for DHCP are ON (default) or OFF.
DHCP ON (Default): If DHCP is ON (the factory default setting), the E5810
will try to obtain an IP address from a DHCP Server. If this fails, the
E5810 will use its static IP address. If DHCP is ON and a DHCP Server is
found, the manually configured IP Address, Subnet Mask, and Default
Gateway parameters are not used by the E5810 during startup and thus
are not required settings.

DHCP OFF: If DHCP is OFF or unavailable, during startup the E5810 will
use the static IP address that may be input in the Configuring your E5810
LAN/GPIB Gateway page. In this case, the values for the IP Address,
Subnet Mask, and Default Gateway shown in the Configured Value column
of the page will be used during startup.
E5810 Serial
Number
[Factory-Set]
The individual Serial Number assigned at the factory for each E5810. The
Serial Number is printed on a label on the underside of the E5810 and
has the form US12345678.
Ethernet (MAC)
Address
[Factory-Set]
This is the Media Access Control Address, also known as the link-level
address, the Ethernet (station) Address, the LANIC ID and Hardware
Address. This is a unique 48-bit address assigned by the manufacturer
for each Ethernet device. The address is usually 12 hexadecimal
characters, with colon or dash separators between every two characters,
such as “00:30:D3:05:00:23” or “00-30-D3-05-00-23”. The Ethernet
address is printed on a label on the underside of the E5810.
GPIB Address
[21]
This value configures the GPIB bus address of the E5810. This address
is used when transfers are made on the GPIB bus. A SICL client
application can change this value by using the SICL function
IGPIBBUSADDR. The GPIB address value can be any number 0 through
30.
GPIB Logical Unit
[7]
This value is the interface logical unit (LU) number of the GPIB interface
in the E5810. It may be used in an Agilent SICL client application’s iopen
statement to uniquely identify the GPIB interface in the E5810. The GPIB
logical unit value can be any number 1 through 255.
GPIB SICL Interface
Name
[gpib0]
This value is the symbolic name of the GPIB interface in the E5810. It is
used in a SICL client application’s iopen operation to symbolically
reference the GPIB interface in the E5810. The maximum length of the
GPIB interface name is 15 characters. If VXI-11 (TCP/IP Instrument
Protocol) is used, the name must be gpib<n>. The names “hpib” or
“hpib7” may be used to more easily support legacy programs, if only
SICL/LAN protocols will be used.

Using E5810A Web Access
Viewing and Modifying Configuration
Parameter
[Default]
Hostname
[None]
Description
This value configures the internet domain name for the E5810.
Hostnames are useful when IP addresses are being assigned by a DHCP
Server, since the Hostname will not change despite DHCP Server
changes and device IP address changes.
If a Hostname is entered, the E5810 will try to register this name when it
boots. The E5810 can only register the Hostname if the network has
Dynamic DNS. If the network does not have Dynamic DNS, this value is
not used. Since you can always use the IP Address or the name (possibly
supplied by another name Server), the Hostname is not a required
configuration value.
You may enter up to 35 characters for the Hostname. The Hostname
must start with a letter and consists of upper and lower case letters and
digits and dashes. There is no default Hostname. If a Hostname is
displayed on the Welcome page, it is a valid Hostname, since one was
found on the network through DNS.
I/O Timeout
[120 sec]
This value sets the Server I/O timeout in seconds. It configures the E5810
to use an I/O timeout of the specified amount of seconds if the client
requests a timeout of infinity. If 0 is specified for this value and the client
requests an infinite timeout, the E5810 will use a timeout of infinity as
requested.
Setting the I/O timeout to 0 is NOT recommended, as this can result in the
E5810 waiting indefinitely for an I/O operation and effectively “hang” the
E5810.
This timeout value may be used to ensure that the E5810 does not wait
indefinitely for an I/O operation. It also allows the E5810 to detect certain
network events (such as when a client connection is dropped) that may
otherwise go undetected. If the E5810 detects such a condition, it will
release any resources, such as locks, associated with the client.
This value also allows the E5810 to detect certain network events, such
as when a client connection is dropped. If the E5810 detects such a
condition, it will release any resources, such as locks, associated with the
client. The factory default setting is 120 sec.

Parameter
[Default]
IP Address
[169.254.58.10]
Description
This value is the Internet Protocol (IP) address of the E5810. The IP
address is a required value and is used for all IP and TCP/IP
communications with the E5810. The IP address is represented in dotted
decimal notation (for example, 154.140.222.201). This number is assigned
by the System Administrator. The E5810 has a default static IP address
of 169.254.58.10.
LAN traffic to the E5810 will be routed by the IP Address or by using a
Hostname that may be provided by a DNS name Server which is mapped
to this IP Address. The current E5810 IP Address may have been
established in one of two ways:
The IP address was provided by a DHCP Server during startup
(dynamic IP address).
The IP address shown on the Current Configuration of the E5810
LAN/GPIB Gateway page was used. This was set at the factory to
169.254.58.10. If DHCP will not be used, the IP address should be
set for your network.
LAN Keepalive
[7200 sec]
This value sets the LAN connect timeout in seconds. The E5810 may use
the TCP keepalive timer of the TCP/IP protocol stack to determine if a
client is still reachable. By specifying this configuration value, the E5810
turns on the keepalive timer when connecting to the client.
After the specified time, if there has been no activity on the connection,
the E5810 sends keepalive probes to the client to determine if it is still
alive. After a specified amount of time, the connection will be marked as
down (“dropped”), and the E5810 will release any resources which were
allocated to the associated client.
A value of 0 means no timeout is set. Thus, the E5810 will wait forever
and no keepalive probes are sent. If this value is set, it is recommended
that the largest value be used which still meets the application’s need for
unreachable client detection.
Smaller LAN Keepalive values will generate more keepalive probes
(network traffic), using more of the available network bandwidth.
Allowable values are 0 and greater than or equal to 600 seconds (10
min). The factory default setting is 7200 sec (2 hrs).

Description
*IDN?
ID String. Returns the ID string for the selected IEEE-488.2 compliant
instrument.
Device Clear
Device Clear. Sometimes communication with an instrument may be
impeded. This can occur for a wide variety of reasons. Sending a Device
Clear to the instrument usually solves this problem and restores proper
communication with the instrument. If you encounter an error while doing a
Formatted I/O operation, you can send a Device Clear to ensure proper
instrument communication is restored.
Read STB
Read Status Byte. Returns the decimal and hexadecimal value of the
IEEE-488.2 compliant instrument's Status Byte. Many instruments that
support Formatted I/O also have the ability to read the Status Byte. This
returns information on the status of the instrument, such as error status
and/or busy status. See your instrument manuals for status byte codes.
SYST:ERR?
System Error. Returns a SCPI system error for a SCPI compliant
instrument. A “0 No errors” return is sent to show no system errors.
Clear History
Clear the Display. Clears the (History) display of all previous queries.
Clear ALL
Pending
Operations
Clear All Pending Operations. Clears all pending operations on instruments
connected to the E5810. This operation expires all existing timeouts on all
devices connected to the E5810. Taking this action may affect other users
currently using the E5810. A password dialog box will appear that asks you
if you really want to do this action.
Timeout
Change instrument Timeout. A timeout value is used to limit the amount of
time for an I/O operation to complete. The I/O Timeout value, as set on the
Configuring your E5810 LAN/GPIB Gateway page, may not be long enough
for some instrument activities to complete. Setting a longer timeout here
tells the E5810 to wait a longer time for the instrument to finish.
As an alternative, doing a separate Send and Receive may also work. Also,
if the configuration value is too long, you may force a shorter timeout here
for faster troubleshooting of instrument tests, etc. To set a different timeout,
enter a Timeout value in the Timeout text box. This value is used for all
commands issued to an instrument from this page. The valid timeout range
is 1 to 60 seconds.

Updating E5810A Firmware
This section gives guidelines to update your E5810 firmware to the latest
version.
NOTE
Do not update your E5810 firmware unless you have a specific need to
do so, such as defect repair or instrument enhancements. If the firmware
update fails, the E5810 reverts to its original firmware version.
The E5810 uses standard FTP (File Transfer Protocol) to perform updates.
The E5810 acts as an FTP client and searches for an FTP Server that
contains the E5810 firmware image. Agilent maintains a publicly accessible
FTP Server that contains the latest E5810 firmware at:
ftp.agilent.com, login: anonymous, password:
<your e-mail address>
Procedure to
Update E5810
Firmware
The latest E5810 firmware is at /pub/e5810/e5810_latest_firmware.hex
and is called "e5810_latest_firmware.hex". Prior versions are also
available in this ftp directory.
If you cannot reach the Agilent FTP Server from your E5810, you can use a
any standard FTP Server that is available, provided you have an image of
the firmware. The requirements are an FTP Server, an image of the E5810
firmware, and a LAN connection between the E5810 and the FTP Server.
The procedure to update E5810 firmware depends on whether or not the
Agilent FTP site is accessible from the E5810. This, in turn, depends on
how your network is configured. The E5810 FTP client used to upload new
firmware is a standard FTP client and currently does not support proxies.
This means that anyone behind a firewall will most likely not be able to
directly access the Agilent FTP site.
A description of the two procedures to update E5810 firmware follows.
If the Agilent FTP site is accessible from the E5810, see “Agilent
FTP Site is Accessible From E5810”
If the Agilent FTP site is not accessible from the E5810, see “Agilent
FTP Site is not Accessible From E5810”

If the Update was Unsuccessful. If the last message in the system log
indicates the E5810 was trying to update firmware, the firmware process
was not successful and the E5810 firmware will revert to its original
(factory-set) version. In this case, try the following:
a
Verify FTP Server Address. Verify that the Firmware FTP Server
domain name is correct and fully qualified. A domain name is a
symbolic name for an IP address. For example, 'ftp.agilent.com' is
the domain name for IP Address 192.6.143.21. Try to manually use
FTP to access the FTP Server that contains the E5810
firmware.Verify that the firmware file is in the proper directory and
that the firmware file has the correct name.
b Manually Enter DNS Server Address. For the firmware update
process to use a domain name, the E5810 must have a DNS
(Domain Name Server) setup. If you statically configured the
IP Address for the E5810, you will need to manually enter the DNS
Server address in the Configuring your E5810 LAN/GPIB Gateway
page.
c
Use the IP Address. Try using the IP Address of the FTP Server
instead of the domain name.
d Check Login, Password and Firmware Name Entries. Make sure the
login, password, firmware filename are entered correctly. Also,
make sure the login name and password match a valid user
account on the FTP Server.
e
Check Directory Information. Make sure the correct directory
information is present (if needed), such as
“/pub/e5810/e5810_latest_firmware.hex”. If you use directory
information, make sure the directory designator character is correct
for your FTP server. Some FTP servers use “/” (forward slash) and
others use “\” (backslash).

you may need to Enable Javascript, and configure Cache and Page
Refresh, and/or Proxies options on your Web browser. Internet Explorer 6.0
or greater is recommended.
Enabling Javascript The E5810 web server uses Javascript. The E5810 can detect if Javascript

For faster performance, most web browsers cache web pages. If a page is
cached, an image of the web page is stored locally. When you navigate to a
page that has already been viewed, the browser will load the page from it
cache rather than loading it from the network.
Usually, this process works well for static web pages. However, this process
may cause problems for 'dynamically' changing web pages. This problem
may occur when you are navigating using the browser’s forward / back /
refresh options.
Chapter 4
115
Troubleshooting Information
Checking the Network
Doing this usually causes the browser to first look in its cache to see if the
page exists. If the page is cached, the browser displays the page from the
cache instead of going to the network to update changes. Since the E5810
web pages are dynamic in nature, the cache may contain content that is
outdated on modern browsers.
If you see a problem where dynamic pages are not being updated
automatically (for example, click refresh on status page and see the time
since reboot information), the browser should be instructed to check for
newer versions of a web page on each every page visit. Steps for cache and

A proxy is a service running on a computer that takes an information
request from another computer and passes the request on as if the request
was its own. Typically, many companies use proxies to control access from
their internal network to the external Internet.
In some situations, you may not be able to communicate with the E5810 if
you are using a proxy server. Typically, the web page will timeout because
the requested address is not accessible by the network, although the correct
IP address or hostname is entered into the Web browser address field.
To fix this communication problem between the web browser and the E5810
web server, the browser must be informed that any requests to the E5810
should not utilize a proxy. Suggested steps to set proxy notification for some
Internet Explorer version is as follows.

Checking Other Network Problems
There are two additional network checks you may encounter: E5810
operation hangs or SICL timeout is set to 0 (infinite)
E5810 Operation
Hangs
The E5810 has a single Remote IO Server servicing both GPIB and RS-232
interfaces. Thus, if either interface “hangs” in an operation where a timeout
has been set to a long time period, there is no more communication on either
interface (GPIB or RS-232) until the pending transaction completes (via
normal completion, or a timeout). That is, a pending operation on the
RS-232 interface will hang GPIB operations, and vice-versa.
To avoid this, set as short a timeout as possible for both the GPIB and
RS-232 interfaces, so the E5810 is not left in a hung situation awaiting a
pending I/O operation. For example, a detached (or loose) GPIB or RS-232
cable can cause an operation to hang if timeouts are set too high.
Setting long timeouts with the E5810 is not recommended. However, if a
long timeout period is required for your programming application, you can
set the timeout with:
VISA: viSetAttribute() and VI_ATTR_TMO_VALUE attribute
SICL: itimeout()
See the Agilent VISA User’s Guide for a description of the VISA command.
See the Agilent SICL User’s Guide for Windows for a description of the SICL
command.

Troubleshooting Information
Checking the Network
SICL Timeout
Set to 0 (infinite)
The E5810 uses the LAN maximum timeout configured in Connection
Expert’s LAN interface for its default or infinite timeout. If a SICL
itimeout(id,0) command is used (where a 0 timeout value is an infinite
timeout) the E5810 will use the I/O Timeout (sec): value set on the Current
Configuration of E5810 LAN/GPIB Gateway page. The default timeout value is
120 sec. Setting the I/O Timeout (sec): value to 0 enables infinite timeouts
from SICL applications.
NOTE
It is highly recommended you not set an infinite timeout which can cause
the E5810 to become unresponsive due to a pending operation that will
never timeout.
Setting long timeouts with the E5810 is discouraged. However, if a long
timeout period is required for your application, you can set the timeout with
these commands:
VISA: viSetAttribute(vi, attr, attrState)
where: attr is VI_ATTR_TMO_VALUE
attrState is a large value
SICL: itimeout(id,tval),
number

Checking PC Client Connections
Checking PC Client Connections
Even if the E5810 has been successfully configured and the configuration
has been verified, individual PC clients may still have problems connecting
to the E5810. This section gives guidelines to check PC client connections
to the E5810, including:
Verifying PC Client Connections
Checking syslog Messages
Runtime Error Messages
Verifying PC Client Connections
Even if the E5810 has been successfully configured and the configuration
has been verified, individual clients may still have problems getting a
connection to the E5810.
How to Verify PC
Client Connections
To verify that the PC client system has network access to the E5810, open
the Web Browser on the client PC and type in the E5810 IP address (or
hostname, if known) on the browser’s address line. If the E5810 Welcome
page appears, this client PC has network connection to the E5810. Repeat
this step for each client PC on the network.
NOTE
You can also use the Telnet utility or a ping command from a DOS
command window to check for network connections to the E5810. See
Appendix B, “Using the Telnet Utility” for details.
If the Welcome page times out, this indicates the client PC was unable to
connect to the E5810. The E5810 may be on a different subnet than the
client or the E5810 may have incorrect network configuration values. In this
case, try the ping command. A typical example follows. If the ping command
does not work, contact your System Administrator.

configuration values are correct. Or, you can use Connection Expert. To
open Connection Expert, click the IO icon on the Windows taskbar
notification area and then click Agilent Connection Expert.
viopen fails:
No connection
The connection to the E5810 failed for one of these reasons:
A TCP/IP network timeout occurred because the network
connection is down or the E5810 is down.
The E5810 has reached its maximum concurrent client
connections (16) and this new connection was refused. You may
need to have a client close its connection or you may need to
reboot the E5810 to close all client connections to allow a new
connection to be made. Up to 16 sessions can be in use at any
one time.
viopen fails:
Timeout
The client has timed out. The E5810 has not responded within the
appropriate timeout time because:
The network connection is down or the E5810 is down.
The server is busy performing an operation for a different client.
You may need to increase the Client delta timeout configuration
value on the LAN client PC. To set this value, click the IO icon on
the Windows taskbar notification area and then click Agilent

terminate its connection or you may need to reboot the E5810 to close
all client connections to reclaim resources. Rebooting will disconnect all
other users accessing the E5810.
I/O operation fails:
No connection
The connection to the E5810 failed because:
The network connection is down or the E5810 is down and a
network timeout occurred.
The E5810 was powered off and then on or an E5810 reboot was
executed, either of which terminates any open client connections.

The client may be attempting a transaction to a non-existent or
powered-off device. Check the address used, as well as the
status of the device.
The network connection or the E5810 has gone down since the
previous I/O operation.
The I/O timeout specified is not long enough for the transaction to
complete. You may need to verify that the E5810 I/O timeout
configuration value is long enough if the client specified a timeout
value of infinity.

Description/Actions
E5810 appears
to be hung
There are several possible causes. For all of the following, use of client
timeouts and/or E5810 timeouts (the I/O timeout and LAN timeout
configuration values) can be used to ensure that the E5810 will not
“hang” indefinitely.
If you determine that the E5810 is truly hung, you may be able to
free it by terminating a particular client connection at the client,
thus freeing the resources to allow the E5810 to proceed.
Otherwise, you can press the Clear ALL Pending Operations
button on the Find and Control Instruments Connected to your
E5810 Web page or you can reboot the E5810.
The network connection to the E5810 has been broken.
The E5810 may be attempting a transaction to a non-existent or
powered-off device. Check the address used, as well as the
status of the device.
The E5810 is busy performing a very long transaction to a (slow)
device, or it is waiting for input from a device.
A client may be waiting for access to a device/interface locked by
another client. Check for possible deadlock situations and, if
possible, make sure the clients owning locks and the connections
to those clients are still up and functioning. You can check the
current session by clicking the Session Status icon to display the
E5810 LAN/GPIB Gateway Status Web page.

Glossary
A
address
A string uniquely identifying a particular interface or a device on that
interface which is interpreted at the E5810 LAN/GPIB Gateway to identify
the interface or device.
ASRL
For the E5810, ASRL is synonymous with RS-232. See RS-232.
B
bridge
C
client
In telecommunication networks, a bridge is a product that connects a
local area network (LAN) to another local area network that uses the
same protocol (for example, Ethernet or token ring). You can envision a
bridge as being a device that decides whether a message from you to
someone else is going to the local area network in your building or to
someone on the local area network in the building across the street. A
bridge examines each message on a LAN, “passing” those known to be
within the same LAN, and forwarding those known to be on the other
interconnected LAN (or LANs).
Part of the client/server model used in distributed computing. A client is a
computer system that requests services from a server computer system,
such as I/O application requests, networking requests, etc.
controller
A computer used to communicate with a remote device such as an
instrument. In the communications between the controller and the device,
the controller is in charge of and controls the flow of communication that
is, it does the addressing and/or other bus management). The controller
acts as the remote I/O client to the E5810 server.
D
device
A unit that receives commands from a controller. Typically a device is an
instrument but could also be a computer acting in a non-controller role, or
another peripheral such as a printer or plotter.
144
Glossary
DHCP
Short for Dynamic Host Configuration Protocol, a protocol for assigning
dynamic IP addresses to devices on a network. With dynamic
addressing, a device can have a different IP address every time it
connects to the network.
In some systems, the device's IP address can even change while it is still
connected. DHCP also supports a mix of static and dynamic IP
addresses.
Dynamic addressing simplifies network administration because the
software keeps track of IP addresses rather than requiring an
administrator to manage the task. This means that a new computer can
be added to a network without manually assigning it a unique IP address.
DHCP client support is built into Windows workstations.
DNS
Short for Domain Name System (or Service), an Internet service that
translates domain names into IP addresses. Because domain names are
alphabetic, they are easier to remember. The Internet, however, is really
based on IP addresses. Every time you use a domain name, therefore, a
DNS service must translate the name into the corresponding IP address.
For example, the domain name www.example.com might translate to
198.105.232.4. The DNS system is a distributed system. If one DNS
server does not know how to translate a particular domain name, it asks
another one, and so on, until the correct IP address is returned.
E
Ethernet (MAC) Address
F
Friendly Name
The Media Access Control Address, also known as the link-level
address, the Ethernet (station) Address, the LANIC ID and Hardware
Address. This is a unique 48-bit address assigned by the manufacturer
for each Ethernet device. It is usually displayed as 12 hexadecimal
characters, sometimes with colon or dash separators between every two
characters, such as “00:03:d3:00:00:17” or “00-03-d3-00-00-17”.
The “UPnP Friendly Name” of the E5810 that will automatically be
displayed on Universal Plug and Play (UPnP) enabled LAN hosts. When
the E5810 is connected to the LAN, it broadcasts its presence to the
network if UPnP is enabled. UPnP clients will then see the name and
description of this E5810 in My Network Places. A Friendly Name can be
up to 39 characters including spaces.
Glossary
145
G
gateway
Hardware that permits a network connection between the LAN that your
computer understands and the instrument specific interface that your
device understands.
Gateway IP Address
This parameter is the IP Address of the default subnet gateway that
allows the E5810 to communicate with systems that are not on the local
subnet. Thus, this is the default subnet gateway where packets are sent
that are destined for a device not on the local subnet, as determined by
the subnet mask setting. Only one default subnet gateway can be
configured. A value of 0.0.0.0 indicates that no subnetting is to be done.
H
Hostname
This parameter is the Internet domain name for the E5810. Depending
upon the type of servers in the network, you may be able to use this
name to communicate with the E5810. However, since you can always
use the IP Address or the name supplied by another name server, the
Hostname is not a required configuration value.
You may enter up to 15 characters for the Hostname. The Hostname
must start with a letter and consists of upper and lower case letters and
digits and dashes. The default Hostname is “E5810-” plus the last four
characters of the Ethernet (MAC) address, such as E5810-e40c.
hub
A common connection point for devices in a network. Hubs are
commonly used to connect segments of a LAN. A hub contains multiple
ports. When a packet arrives at one port, it is copied to the other ports so
that all segments of the LAN can see all packets.
- Passive hubs serve simply as a conduit for the data, enabling it to go
from one device (or segment) to another.
- Intelligent hubs include additional features that enables an administrator
to monitor the traffic passing through the hub and to configure each port
in the hub. Intelligent hubs are also called manageable hubs.
- Switching hubs actually read the destination address of each packet
and then forward the packet to the correct port.
146
Glossary
I
instrument
A device that accepts commands and performs a test or measurement
function.
interface
A connection and communication media between devices and
controllers, including mechanical, electrical, and protocol connections.
IP address
An Internet Protocol (IP) address is an identifier for a computer or device
on a TCP/IP network. Networks using the TCP/IP protocol route
messages based on the IP address of the destination. The format of an
IP address is a 32-bit numeric address written as four numbers
separated by periods. Each number can be zero to 255. For example,
1.160.10.240 could be an IP address.
Within an isolated network, you can assign IP addresses at random as
long as each one is unique. However, connecting a private network to the
Internet requires using registered IP addresses (called Internet
addresses) to avoid duplicates. The four numbers in an IP address are
used in different ways to identify a particular network and a host on that
network. The InterNIC Registration Service assigns Internet addresses
from the following three classes.
Class A - supports 16 million hosts on each of 127 networks
Class B - supports 65,000 hosts on each of 16,000 networks
Class C - supports 254 hosts on each of 2 million networks
Glossary

L
LAN
Local Area Network. A computer network that spans a relatively small
area. Most LANs are confined to a single building or group of buildings.
However, one LAN can be connected to other LANs over any distance
via telephone lines and radio waves. A system of LANs connected in this
way is called a wide-area network (WAN).
Most LANs connect workstations and personal computers. Each node
(individual computer) in a LAN has its own CPU with which it executes
programs, but it also is able to access data and devices anywhere on the
LAN. This means that many users can share expensive devices, such as
laser printers, as well as data. Users can also use the LAN to
communicate with each other, by sending e-mail or engaging in chat
sessions.
There are many different types of LANs, Ethernets being the most
common for PCs. Most Apple Macintosh networks are based on Apple's
AppleTalk network system, which is built into Macintosh computers. The
following characteristics differentiate one LAN from another:
topology: The geometric arrangement of devices on the network. For
example, devices can be arranged in a ring or in a straight line.
protocols: The rules and encoding specifications for sending data. The
protocols also determine whether the network uses a peer-to-peer or
client/server architecture.
media: Devices can be connected by twisted-pair wire, coaxial cables, or
fiber optic cables. Some networks do without connecting media
altogether, communicating instead via radio waves.
LANs are capable of transmitting data at very fast rates, much faster than
data can be transmitted over a telephone line. However, the distances
are limited and there is also a limit on the number of computers that can
be attached to a single LAN.
lock
A state that prohibits other users from accessing a resource, such as a
device or interface.
logical unit
A logical unit is a number associated with an interface. In Agilent SICL, a
logical unit uniquely identifies an interface. Each interface on the
controller must have a unique logical unit.
148
Glossary
N
network protocols
The E5810 supports these network protocols: ARP, DHCP, DNS, FTP,
HTTP, ICMP, and RPC.
ARP: Short for Address Resolution Protocol, a TCP/IP protocol used to
convert an IP address into a physical address (called a DLC address),
such as an Ethernet address.
DHCP: See DHCP
DNS: See DNS
FTP: Abbreviation of File Transfer Protocol, the protocol used on the
Internet for sending files.
HTTP: Short for HyperText Transfer Protocol, the underlying protocol
used by the World Wide Web. HTTP defines how messages are
formatted and transmitted, and what actions Web servers and browsers
should take in response to various commands.
ICMP: Short for Internet Control Message Protocol, an extension to the
Internet Protocol (IP) defined by RFC 792. ICMP supports packets
containing error, control, and informational messages. The PING
command, for example, uses ICMP to test an Internet connection.
RPC: Abbreviation of remote procedure call, a type of protocol that allows
a program on one computer to execute a program on a server computer.
Using RPC, a system developer need not develop specific procedures
for the server. The client program sends a message to the server with
appropriate arguments and the server returns a message containing the
results of the program executed.
P
proxy server
A server that sits between a client application, such as a Web browser,
and a real server. It intercepts all requests to the real server to see if it
can fulfill the requests itself. If not, it forwards the request to the real
server. Proxy servers have two main purposes:
Improve Performance: Proxy servers can dramatically improve
performance for groups of users, since a proxy server saves the results
of all requests for a certain amount of time. Consider the case where both
user X and user Y access the Web through a proxy server. First user X
requests a certain Web page, which we will call Page 1. Sometime later,
user Y requests the same page.
Glossary
149
Instead of forwarding the request to the Web server where Page 1
resides, which can be a time-consuming operation, the proxy server
returns the Page 1 it already fetched for user X. Since the proxy server is
often on the same network as the user, this is a much faster operation.
Real proxy servers support hundreds or thousands of users.
Filter Requests: Proxy servers can also be used to filter requests. For
example, a company might use a proxy server to prevent its employees
from accessing a specific set of Web sites.
R
router
A device that connects any number of LANs. Routers use headers and a
forwarding table to determine where packets go. They use Internet
Control Message Protocol (ICMP) to communicate with each other and
configure the best route between any two hosts. Very little filtering of data
is done through routers. Routers do not care about the type of data they
handle. Routers often have DHCP Server capability.
RS-232
Short for recommended standard-232C, a standard interface approved
by the Electronic Industries Association (EIA) for connecting serial
devices. The standard is also referred to as RS-232C, or just RS-232.
For RS-232, the device that connects to the interface is called a Data
Communications Equipment (DCE) and the device to which it connects
(such as a computer) is called a Data Terminal Equipment (DTE).
The RS-232 standard supports two types of connectors - a 25-pin D-type
connector (DB-25) and a 9-pin D-type connector (DB-9). The type of
serial communications used by PCs requires only 9 pins so either type of
connector will work equally well.
S
server
Part of the client/server model used in distributed computing. The server
is a computer system designated to act as a main servicer of requests
from other client computer systems, such as I/O application requests,
networking requests, and so forth.
SICL
The Agilent Standard Instrument Control Library, which is software used
for I/O application programming. SICL is part of the Agilent IO Libraries
Suite.
150
Glossary
SRQ
Service Request. An asynchronous request (an interrupt) from a remote
device indicating that the device requires servicing.
subnet
A portion of a network that shares a common address component. On
TCP/IP networks, subnets are defined as all devices whose IP addresses
have the same prefix. For example, all devices with IP addresses that
start with 100.100.100. would be part of the same subnet. Dividing a
network into subnets is useful for both security and performance reasons.
IP networks are divided using a subnet mask.
subnet mask
A mask used to determine to what subnet an IP address belongs. An IP
address has two components: the network address and the host address.
For example, consider the IP address 150.215.017.009. Assuming this is
part of a Class B network, the first two numbers (150.215) represent the
Class B network address and the second two numbers (017.009) identify
a particular host on this network.
Subnetting enables a System Administrator to further divide the host part
of the address into two or more subnets. In this case, a part of the host
address is reserved to identify the particular subnet.
For example, the full address for 150.215.017.009 is
10010110.11010111.00010001.00001001. The Class B network part is
10010110.11010111 and the host address is 00010001.00001001. If this
network is divided into 14 subnets, the first four bits of the host address
(0001) are reserved for identifying the subnet.
The subnet mask is the network address plus the bits reserved for
identifying the subnetwork. (By convention, the bits for the network
address are all set to 1, though it would also work if the bits were set
exactly as in the network address.) In this case, the subnet mask is
11111111.11111111.11110000.00000000.
It is called a mask because it can be used to identify the subnet to which
an IP address belongs by performing a bitwise AND operation on the
mask and the IP address. The result is the subnetwork address:
Subnet Mask 255.255.240.000
11111111.11111111.11110000.00000000
IP Address 150.215.017.009
10010110.11010111.00010001.00001001
Subnet Address 150.215.016.000 10010110.11010111.00010000.00000000
The default subnet mask for the E5810 is 255.255.0.0
Glossary
151
switch
A device that filters and forwards packets between LAN segments.
Switches operate at the data link layer (layer 2) and sometimes the
network layer (layer 3) of the OSI Reference Model and therefore support
any packet protocol. LANs that use switches to join segments are called
switched LANs or, in the case of Ethernet networks, switched Ethernet
LANs. A hub connects all the devices on its “ports” together.
A switch is a bit smarter, as it understands when two devices (out of four,
five, eight, sixteen, or even more) want to talk to each other and gives
them a switched connection.
symbolic name
A name corresponding to a single interface. This name uniquely
identifies the interface on a controller or gateway. If there is more than
one interface on the controller or gateway, each interface must have a
unique symbolic name.
U
Universal Plug and Play
Universal Plug and Play (UPnP) is an open industry standard that uses
Internet and Web protocols to enable devices such as PCs, peripherals,
intelligent appliances, and wireless devices to be plugged into a network
and automatically know about each other.
UPnP is an architecture for pervasive peer-to-peer network connectivity
of PCs and intelligent devices or appliances. UPnP builds on Internet
standards and technologies, such as TCP/IP, HTTP, and XML, to enable
LAN devices to automatically connect with one another and work
together.
With UPnP, when a user plugs a device into the network, the device will
configure itself, acquire a TCP/IP address, and use a discovery protocol
based on the Internet's Hypertext Transfer Protocol (HTTP) to announce
its presence on the network to other devices. UPnP devices use
Extensible Markup Language (XML) to establish a common language, or
“protocol negotiation”, to talk to each other and determine capabilities.
The E5810 has two options for Universal Plug and Play (UPnP):
Option ON: The E5810 is configured as a UPnP device and provides
information to the network about itself via an XML description when
mounted to the network.
152
Glossary
Option OFF: The E5810 is not UPnP capable and will not announce
its presence as a UPnP device when mounted to the network.
